Some clubs have signed some high profile free agents (Norwich / Scum) which will have cost them a fair amount (or will spread over contract) but are probably listed as frees.
Some consideration has to go into outgoings too. Our net spend is low so far having brought in many for Obafemi, Whittaker, Joseph, Lati, Martin plus coaches. Our spend will be hugely negative should Piroe leave.
And also, this is from a low base to start off with, with the squad being short on numbers and depth and being imbalanced.
So I don't think you can look into our current spend and it's fairly lofty position in spend compared to others and it be particularly impressive or relevant.
